of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand

Securities who thereafter wishes to include all or a portion of such Apache Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Apache Holder that

Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a
Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of
all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. 
 2.1.2
Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the
Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any)
to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the
extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.2 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the Company by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

(30) days after the Contribution Closing Date, file a Registration Statement under the Securities Act to permit the public resale of all the Registrable Securities held by the Holders from time to time as permitted by Rule 415 under the
Securities Act (or any successor or similar provision adopted by the Commission then in effect) on the terms and conditions specified in this subsection 2.1.3 and shall use its commercially reasonable efforts to cause such
Registration Statement to be declared effective as soon as practicable after the filing thereof, but in any event no later than the earlier of (i) ninety (90) days (or one hundred and twenty (120) days if the Commission notifies the
Company that it will “review” the Registration Statement) after the Contribution Closing Date and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission
that such Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”). The Registration Statement filed with the Commission pursuant to

S-3”), or, if Form S-3 is not then available to the Company, on Form S-1 (“Form S-1”) or on such other form of registration statement as is then available to effect a Registration for resale of the Registrable Securities; provided, however, that if the Company has
filed the Registration Statement on Form S-1 and subsequently becomes eligible to use Form S-3 or any equivalent or successor form, the Company shall (i) file a
post-effective amendment to the Registration Statement converting such Registration Statement on Form S-1 to a Registration Statement on Form S-3 or any equivalent


  
 8 













 
or successor form or (ii) withdraw the Registration Statement on Form S-1 and file a subsequent Registration Statement on Form S-3 or any equivalent or successor form, and shall contain a Prospectus in such form as to permit any Existing Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any
successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such Registration Statement. A Registration Statement filed pursuant to this subsection 2.1.3 shall provide for the
resale pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall use its reasonable best efforts to cause a Registration Statement filed pursuant to this subsection 2.1.3 to remain
effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available, for the resale of all the Registrable Securities
held by the Holders until all such Registrable Securities have ceased to be Registrable Securities or the earlier termination of this Agreement pursuant to Section 5.7. As soon as practicable following the effective date of
a Registration Statement filed pursuant to this subsection 2.1.3, but in any event within three (3) business days of such date, the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a
Registration Statement filed pursuant to this subsection 2.1.3 (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange
Act and will not contain a Misstatement (in the case of any Prospectus contained in such Registration Statement, in the light of the circumstances under which such statement is made). 

2.1.4 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Offering pursuant to a Demand
Registration, in good faith, advises the Company, the Demanding Holders, and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire
to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell, and the Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back
registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in such Underwritten Offering without adversely affecting the proposed offering price,
the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall
include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and Requesting Holders (if any) (if such amount exceeds the Maximum Number of Securities, pro rata based on the respective number
of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have
requested be included in such Underwritten Offering) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the

Registration and shall use its reasonable best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Apache Holders pursuant to this subsection
2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance

the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration has been requested
pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3; provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering, unless such Underwritten Offering is reasonably expected to result in gross
proceeds in excess of $10 million. Within five (5) days of the Company’s receipt of a written request from an Apache Holder or Apache Holders of Registrable Securities for a Registration on Form
S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Apache Holders of Registrable Securities, and each Apache
Holder of Registrable Securities who thereafter wishes to include all or a portion of such Apache Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing,
within ten (10) days after the receipt by the Apache Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a
Registration on Form S-3, the Company shall register all or such portion of such Apache Holder’s Registrable Securities as are specified in such written request, together with all or such portion of
Registrable Securities of any other Apache Holder or Apache Holders joining in such request as are specified in the written notification given by such Apache Holder or Apache Holders; provided, however, that the Company shall not be obligated to
effect any such Registration pursuant to this Section 2.3 if (i) a Form S-3 is not available for such offering; or (ii) the Apache Holders of Registrable Securities, together with the Holders of
any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $10 million. 

2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the
Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to
the Holders prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively 

  
 12 













 
employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) pursuant to subsection 2.1.2, Holders have requested an
Underwritten Offering and the Company and Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the majority of the Board such Registration would be seriously
detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by
the chairman of the Board stating that in the good faith judgment of the majority of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to
defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days. Notwithstanding anything to the contrary contained in this Agreement, no
Registration shall be effected or permitted and no Registration Statement shall become effective, with respect to any Registrable Securities held by any Existing Holder, until after the expiration of the Founder Shares
Lock-up Period or the Private Placement Lock-up Period, as the case may be. 

ARTICLE III 
 COMPANY
PROCEDURES 
 3.1 General Procedures. If the Company is required to effect the Registration of Registrable Securities, the
Company shall use its reasonable best efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as
possible: 
 3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable
Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities have ceased to be Registrable Securities or the earlier termination of this Agreement
pursuant to Section 5.7; 
 3.1.2 prepare and file with the Commission such amendments and post-effective
amendments to the Registration Statement, and such supplements to the Prospectus, as may be requested by the Holders or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the
registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the
intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus; 
 3.1.3 prior to filing a
Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and one legal counsel to such Holders, copies
of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents 

  
 13 













 
incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of
Registrable Securities included in such Registration or the one legal counsel for such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders; 

3.1.4 prior to any public offering of Registrable Securities, use its reasonable best efforts to (i) register or qualify the Registrable
Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their
intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be
necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or
take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject; 

3.1.5 use its reasonable best efforts to cause all such Registrable Securities to be listed on each securities exchange or automated quotation
system on which similar securities issued by the Company are then listed; 
 3.1.6 provide a transfer agent or warrant agent, as applicable,
and registrar for all such Registrable Securities no later than the effective date of such Registration Statement; 
 3.1.7 advise each
seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or
threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such
Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or one counsel on behalf of such
sellers; 
 3.1.9 notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under
the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in
Section 3.4 hereof; 

  
 14 













 3.1.10 permit a representative of the Holders (such representative to be selected by a
majority of the participating Holders), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such Person’s own expense, in the preparation of the Registration Statement, and
cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such
representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 

3.1.11 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an
Underwritten Offering, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 
 3.1.12 on the
date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated as of such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent
or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request
and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders; 

3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form on terms agreed to by the Company, with the managing Underwriter of such offering; 
 3.1.14 make available to its security
holders, as soon as reasonably practicable, an earnings statement (which need not be audited) covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective
date of the Registration Statement which satisfies the provisions of Section 11 (a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million, use its
reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and 

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in
connection with such Registration. 

  
 15 













 3.2 Registration Expenses. The Registration Expenses of all Registrations shall be
borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter
marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders. 

3.3 Requirements for Participation in Underwritten Offerings. No Person may participate in any Underwritten Offering for equity
securities of the Company unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires,
powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. 

3.4 Suspension of Sales; Adverse Disclosure. 

3.4.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders
shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such
supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed (any such period, a “Suspension Period”). 

3.4.2 If the filing, initial effectiveness or continued use of (including in connection with any Underwritten Offering) a Registration
Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond
the Company’s control, then the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of (including in connection with any Underwritten Offering), such
Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose (any such period, a “Blackout Period”). In the
event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale
or offer to sell Registrable Securities. 
 3.4.3 The Company shall immediately notify the Holders of the expiration of any period during
which it exercised its rights under this Section 3.4. Notwithstanding anything to the contrary in this Section 3.4, in no event shall any Blackout Periods and any Suspension Periods continue for
more than ninety (90) days in the aggregate during any 365-day period. 
 3.5 Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and


  
 16 













 
complete copies of all such filings (the delivery of which will be satisfied by the Company’s filing of such reports on the Commission’s EDGAR system). The Company further covenants
that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall
deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE IV 

INDEMNIFICATION AND CONTRIBUTION 

4.1 Indemnification. 

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors, and
each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact
contained in any Registration Statement, Prospectus, preliminary Prospectus, or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and
directors, and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder. 

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and
officers and agents, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any
untrue statement of material fact contained in the Registration Statement, Prospectus, preliminary Prospectus, or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the
obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such
Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors, and each Person who controls such Underwriters (within the
meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 
  

  
 17 













 4.1.3 Any Person entitled to indemnification herein shall (i) give prompt written
notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not
materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified
party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified
parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and
such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all
liability in respect to such claim or litigation. 
 4.1.4 The indemnification provided for under this Agreement shall remain in full force
and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the Transfer of securities. The Company and each Holder of
Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is
unavailable for any reason. 
 4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying
party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities, and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall
contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities, and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified
party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified
party’s relative intent, knowledge, access to information, and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of
the net proceeds received by 

  
 18 













 
such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include,
subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges, or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties
hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations
referred to in this subsection 4.1.5. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection
4.1.5 from any Person who was not guilty of such fraudulent misrepresentation. 
 ARTICLE V 

MISCELLANEOUS

requested, (ii) delivery in person or by courier service providing evidence of delivery, or (iii) transmission by hand delivery, electronic mail, telecopy, telegram or facsimile. Each notice or communication that is mailed, delivered, or
transmitted in the manner described above shall be deemed sufficiently given, served, sent, and received, in the case of mailed notices, on the third business day following the date on which it is mailed and, in the case of notices delivered by
courier service, hand delivery, electronic mail, telecopy, telegram or facsimile, at such time as it is delivered to the addressee (with the delivery receipt or the affidavit of messenger) or at such time as delivery is refused by the addressee upon
presentation. Any notice or communication under this Agreement must be addressed, if to the Company, to: 2000 Post Oak Blvd., Suite 100, Houston, Texas 77056 or by facsimile at (713) 296-6459, and, if to any
Holder, at such Holder’s address or facsimile number as set forth in the Company’s books and records. Any party may change its address for notice at any time and from time to time by written notice to the other parties hereto, and such
change of address shall become effective thirty (30) days after delivery of such notice as provided in this Section 5.1. 
 5.2
Assignment; No Third Party Beneficiaries. 
 5.2.1 This Agreement and the rights, duties and obligations of the Company hereunder may
not be assigned or delegated by the Company in whole or in part. 
 5.2.2 Prior to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, no Existing Holder may assign or delegate such Existing Holder’s rights, duties, or
obligations under this Agreement, in whole or in part, except in connection with a Transfer of Registrable Securities by such Existing Holder to a Permitted Transferee. Subject to the foregoing with respect to Existing Holders, no Holder may assign
or delegate such Holder’s rights, duties, or obligations under this Agreement, in whole or in part, except in connection with a Transfer of Registrable Securities by such Holder to a Permitted Transferee. 

  
 19 













 5.2.3 Neither this Agreement nor any right, remedy, obligation, or liability arising
hereunder or by reason hereof shall be assignable by any party hereto pursuant to any Transfer of Registrable Securities or otherwise, except that each Holder may assign rights hereunder to any Permitted Transferee of such Holder. Any such Permitted
Transferee shall (unless already bound hereby) execute and deliver to the Company an agreement (the “Adoption Agreement”) to be bound by this Agreement in the form of Exhibit A hereto and shall thenceforth be a
“Holder”. 
 5.2.4 This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the
parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 
 5.2.5 This Agreement shall
not confer any rights or benefits on any Persons that are not parties hereto, other than as expressly set forth in this Agreement and Section 5.2 hereof. 

5.2.6 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the
Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) an executed Adoption Agreement. Any Transfer or assignment made other than
as provided in this Section 5.2 shall be null and void. 
 5.3 Counterparts. This Agreement may be executed
in multiple counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

5.4 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES
EXPRESSLY AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO
THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THE AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK. 

5.5 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a
majority-in-interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement
may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, (i) any amendment hereto or waiver hereof that adversely affects one Holder,
solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected and (ii) any amendment
hereto or waiver hereof that adversely affects the Existing Holders or the Apache Holders, as applicable, solely in their respective capacity as Existing Holdings or Apache Holders, as applicable, in a manner that is materially different from the
other Holders, shall require the consent of the 

  
 20 













 
Existing Holders or Apache Holders, as applicable, of a majority-in-interest of the then-outstanding number of
Registrable Securities held by the Existing Holders or Apache Holders, as applicable. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any
rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude
the exercise of any other rights or remedies hereunder or thereunder by such party. 
 5.6 Other Registration Rights. Other than
pursuant to the terms of the Subscription Agreements, the Company represents and warrants that no Person, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to
include such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the account of any other Person. Further, the Company represents and warrants that this Agreement supersedes any
other registration rights agreement or agreement with similar terms and conditions among the parties hereto and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. 

5.7 Term. This Agreement shall terminate, and the parties shall have no further rights or obligations hereunder on (a) the fifth
anniversary of the date hereof or (b) as to any Holder, on such earlier date on which both (i) such Holder, together with such Holder’s Affiliates, owns less than 2,000,000 Registrable Securities and (ii) all Registrable
Securities owned by such Holder and such Holder’s Affiliates may be sold without volume or manner of sale restrictions pursuant to Rule 144 under the Securities Act (or any successor or similar rule adopted by the Commission then in effect).
The provisions of Section 3.5 and Article IV shall survive any termination. 
 5.8 Holder Action. Whenever
the Existing Holders or Apache Holders are entitled to act or refrain from acting, the Existing Holders or Apache Holders, as applicable, shall do so by the determination of a
majority-in-interest of the then-outstanding number of Registrable Securities held by the Existing Holders or Apache Holders, as applicable.
